Replacing filters for pumps
The filter installed in the front plate of the controller protects the aerosol
pumps from dirt. A polluted filter causes the pumps to consume more en-
ergy. Replace the filter at least every 12 months or when the power con-
sumption of the aerosol pumps rises above 50%.
WARNING

If the cover on the filter is open, harmful substances from the filter can es-
cape into the ambient air and endanger persons.
